Trillium. Local (Windows/Linux) or server based (Kubernetes/Docker/Cloudron/Node). + Looks cool – but not necessarily easy to setup on my machine/server.
DokuRoam. Runs on DocuWiki which needs a LAMP setup. + wiki collaboration & ACL. - files stored as .txt not .md so not compatible with Obsidian/etc. (there is a Markdown plugin but it's not been updated in years).
TiddlyWiki has three options. It can be installed in lots of ways, including on Gitlab.
